Mac Pro 2023 - Suitable PCIE SSD drives

Hi All.....I've just bought a Mac Pro 2023 from Apple runnin Vemtura 13.6.5 for Music Production which I do professionally. Originially I wanted to keep things simple by buying PCIE SSD's to just sot into the 5 available PCIE slots....however, I read somewhere that it's best to use as chassis such as the Sonettech 4 slot PCIE....loaded with 990 PRO PCIe 4.0 NVMe M.2 SSD or similar......I've spoken to numerous sellers and everybody suggests different options...whoch doesn't help me as I'm not technical at all so I can't understand the jargon! I have read the Samsung PRO drives are meant for gaming so I would not necessarily need the fastest drives for music production ( I use quite heavy sample libraries though )...I'd certainly rather not spend money unnecessarily having shelled out for the Mac Pro! So.....can anyone recommend some solutions that would work in the mac Pro based on a single 4TB and 2 x 2TB SSD drives, either directly mounted in the PCIE slots, or via a chassis of some kind?

Many thanks
